Enhancing the Car Sounds of Forza Motorsport

Hi everyone,

I’m Nick Wiswell, Audio Director at Turn 10 Studios, and today I want to give you all some details on the audio changes you will hear in Forza Motorsport with the release of Update 13, Mustang Month, and our plans for future updates.

With this blog, I will personally address some of the feedback you have been sending us since we released the game last October. We hear you, and the plans that we are sharing today are in direct response to this – thank you for sharing your honest thoughts.



First, I’d like to give you some insights into the team we have assembled, and some important changes we have made to deliver the best audio experience possible when racing.

I’ve been at Turn 10 Studios since 2010, and I worked directly as Audio Director on Forza Motorsport 4 through Forza Motorsport 6. After that I moved into publishing focused roles working on Forza Horizon and Forza Street, and then into a more technical role before returning to Forza Motorsport full time in March 2023.

When I rejoined the team last year, most of the game’s audio content was already complete, so our efforts were focused on refining the assets we already had. After closely listening to your feedback, we have started incorporating new tools and processes into our audio workflow so we can deliver great sounding, authentic content moving forward. To ensure we have the best people we can leading these efforts, Turn 10 Studios rehired one of our former Sound Designers this past spring to help deliver these new plans.



To give you some context, this sound designer worked on Forza Motorsport (2005) through Forza Motorsport 3, as well as both Forza Motorsport 4 and Forza Motorsport 5 from a central Xbox audio team role. He then joined Polyphony Digital to work on GT Sport and Gran Turismo 7. I first met him when I was at Bizarre Creations working on the Project Gotham Racing games – Xbox’s premier racing game before the days of Forza – and I’m excited to work with him again. Between us, we have made a lot of great sounding racing games – and from some of the posts I’ve seen online, some of you would agree with this!

So, with a new audio leadership team, which includes another lead for our technology and development investments, we are set for the future.

To the state of audio in Forza Motorsport: I will admit that from an authenticity perspective, the game is not where we would like it to be. There are many factors that led to this, but we hope we can set things right going forward. Our goal is to fix these audio issues and ensure that all new cars added to the game are built authentically and uniquely. To achieve this, we have been overhauling our authoring techniques and pipelines so that we can update as many of the most egregious car audio issues as possible.



The initial work on this is now complete, and from Update 13 onwards, all cars added to Forza Motorsport will be built to this newer specification. In addition, a number of cars that have been flagged as inauthentic, both internally at the studio and by the community, will be updated over time.

The cars we are initially updating are with the release of Update 13 include the following:
  • 2022 Pagani Huayra R
  • 2014 Chevrolet #3 Corvette Racing Corvette C7.R
  • 2001 Acura Integra Type R

We have also made changes to the cockpit audio on the 2010 Lexus LFA, following its update in a previous release.



As we look forward to future updates, we will weigh factors such as community feedback, internal priority, upcoming featured cars in game and the availability of suitable recordings.

I’d also like to add that there is a lot of speculation about how the car audio is made and where it is sourced. It is all created from recordings of real cars, either captured on a track or on a dyno. Our library contains over 750 vehicle recordings, and more are being sourced and added every month. The changes we are making are built around how these recordings are being processed and edited, and the way we assemble the recordings back together at runtime to be controlled by the in-game physics engine.

I’m not going to give too much of our secret sauce away, but it’s based on the combined experience of our audio team and software engineers, and we are very happy with the changes we are making.



We hope you like them too, and as always, we look forward to feedback from the community. Also, I’ll be speaking with you all next month – November 7 at 3pm PT – on the official Forza Discord server to go into more detail on our audio development workflows as part of the next “In the Garage” AMA. I hope to see you there.

Forza Motorsport Multiplayer, Rivals and Challenge Hub Calendar for Update 13

[h2]Ford Mustang Challenge Series in Featured Multiplayer[/h2]
Experience the evolution of an automotive icon by jumping behind the wheel of your favorite Mustang era in a decade-spanning multi-class series. Unmissable Pony showdowns await in the Ford Mustang Challenge Series available in the Featured tab throughout Update 13.



There is also a new MX-5 Cup Spec Series. Ideal for beginners and veterans alike, the 2017 Mazda MX-5 Cup is built for single-make racing series, which makes it a thrilling contender in this specialized MX-5 Cup event.

Available under the Open Events tab is a new Cycled Class Series that rotates events daily between P, D, X, C, and E Classes. With the introduction of this series, which will remain available in the game after Mustang Month, players will get to experience a wider range of classes every week. In addition, the dedicated B, A, S, and R Class Series will continue to cycle weekly as before.



Update 13 also sees the first Community Choice selections as part of the Featured Multiplayer event rotation: GTX Sportscar Series, Forza Proto-H, and GTP/C Series. These events were decided on by player voting on the Forza forums; stay tuned for additional voting opportunities for the Community Choice Series in future updates.

This update also includes some additional changes to Featured Multiplayer. We have moved the weekly, cycled one-make series from the Spec tab to Featured tab, increased the race length of Medium races to target 18 minutes (previously 16 minutes), updated Tire Wear Scalar for all Short and Medium length races to 4x – making tire wear consistent across Short, Medium, and Long races, and we have updated the Multi-Class Series to focus solely on ABCS.



Here’s a look at the Featured Multiplayer calendar of upcoming events for Mustang Month:

Starting with Update 13, there will no longer be a Spotlight Series. This change will help improve concurrency across all other available Featured Multiplayer Series. We will continue to showcase Spotlight cars in Career, Rivals, and the Challenge Hub.



Following the release of Update 12, we made the decision to remove Forza GT4 from active Featured Multiplayer events due to the lack of cars and competitiveness within the series. In its place, the Forza Touring Car Spec Series remains available. In the future, we intend to explore alternatives to bring back Forza GT4 racing into Featured Multiplayer, for example, through a GT Multi-Class variation. We will also revisit the standalone Forza GT4 Series once we have a larger car roster to accommodate this Spec Division.

[h2]Pony Up in Steadfast Rivals Events[/h2]
Shave off every possible millisecond from your lap times in Rivals with new events for Mustang Month.



Featuring long straights and challenging banked turns, Sunset Peninsula Raceway is great for testing top speeds and mastering high-speed cornering. Just how fast can you complete a lap on the Full Circuit? That’s your challenge in this month’s Featured Rivals, which puts you behind the wheel of the classic 1982 Ford #6 Zakspeed Roush Mustang IMSA GT.

VIP Members can also show off their driving proficiency at Sunset Peninsula – this time on the Club Reverse Circuit – in the 2018 Chevrolet Camaro ZL1 1LE Forza Edition.



We also have a spooky new event just in time for Halloween. Take back the night in the 2015 Dodge Charger SRT Hellcat at Maple Valley in appropriately 'spooky' conditions. Successfully pass at least 100 Rivals on the leaderboard to unlock the Los Muertos Driver Suit from the Challenge Hub.

Buckle up for a new Legends vs Leaderboard Rivals event, this time with Mobil 1 Pro Driver Juan Pablo Montoya. Race the 1974 Toyota Celica GT at Maple Valley – Reverse Circuit and set a lap to get 50,000 credits! Head to mobil1gaming.com to see Juan Pablo set the lap and more.



As always, look out for Spotlight Rivals featuring the weekly Spotlight cars: the 2024 Ford Mustang GT, 1967 Shelby GT 500, 1995 Ford Mustang SVT Cobra R, and 2013 Ford Shelby GT500.

Update 13 is also the first time that Drift Rivals are available for competition. As noted above, while Drift 101, 102, and 103 events will always be available, future updates will also bring their own Drift Rivals – with A Class Drift and Mediterranean Drift available throughout Mustang Month.
